Fast translation from LTL formulae to Buechi automata

ltl2ba implements an algorithm of P. Gastin and D. Oddoux to generate Buechi automata from linear temporal logic LTL formulae. This algorithm generates a very weak alternating automaton and then transforms it into a Buechi automaton, using a generalized Buechi automaton as an intermediate step. Each automaton is simplified on-the-fly in order to save memory and time. As usual the LTL formula is simplified before any treatment. ltl2ba is more efficient than Spin 3.4.1, with regard to the size of the resulting automaton, the time of the computation, and the memory used.
